Camera-based analytics vs people-counter rentals.
Dedicated 3D sensors are good at the one thing they do: counting a doorway. Events need more than a doorway — here's the honest comparison.
| Capability | Campaign Vision | 3D people-counting sensors |
|---|---|---|
| No hardware to order, ship, or install Sensor vendors ship proprietary units that must be mounted, wired, and returned. | Yes | No |
| Set up on event timelines Temporary builds rarely leave time for a sensor install — camera software connects the day you load in. | Yes | Limited |
| Zone engagement across the whole space Door sensors count crossings at the doorway they cover; zones need a unit per area. | Yes | Limited |
| Dwell quality, attention & journeys | Yes | No |
| Density heatmaps of the floor | Yes | Limited |
| Accurate fixed-entrance counting Both approaches handle entrances well — overhead 3D sensors are genuinely strong here. | Yes | Yes |
| Works in strict no-imagery environments Honest trade-off: depth sensors capture no images at all, which some venues mandate. | No | Yes |
| AI-written client reports | Yes | No |
Where dedicated sensors genuinely win.
- Permanent entrance counting — a store or mall doorway measured for years justifies a fixed sensor install.
- Venues with a strict no-cameras policy: depth sensors capture no imagery of any kind, and for some environments that's non-negotiable.
- Environments where cameras struggle — total darkness, extreme steam or fog.
If you're outfitting a permanent retail doorway, buy the door sensor. If you're producing activations, booths, and pop-ups on event timelines — where the story is engagement, not just entries — software on existing cameras measures more and ships nothing.
Common questions
Aren't dedicated sensors more accurate than cameras?
At a fixed doorway, overhead 3D sensors are genuinely accurate — we say so above. The comparison changes across a whole event footprint: covering zones, dwell, and journeys with door sensors means buying and mounting a unit per area, and they still can't tell you what held anyone's attention. Be skeptical of any vendor — sensor or camera — quoting one accuracy number for every condition; we publish how we define and validate our metrics instead.
Isn't a sensor with no camera automatically better for privacy?
It's simpler, not automatically better. Depth sensors avoid imagery by measuring very little. Camera systems differ in architecture: ours processes frames in memory, stores no video, identifies no one, and keeps only derived numbers — a posture your legal team can review in writing. The right question isn't 'camera or not' but 'what exists after processing?'
We rent sensors per event today. What actually changes?
The logistics disappear: nothing to order, receive, mount, or return-ship — the cameras your venue or production already has become the measurement layer, and coverage is limited by camera views rather than by how many units you rented. Per-event pricing works the same way; the difference is what you get for it.
